Different materials and processes are used by ARP for the manufacture of their products depending on the intended applications. Here is a summary:

• ARP 8740 (Chromoly) : This is the material with an unbeatable price / quality ratio. To date, it offers excellent results and performance for most so-called "racing" applications. Thanks to its various surface treatments and heat treatments used by ARP during the design and manufacture, this material is at a resistance around 200,000 psi.
• ARP 2000 : This high performance steel alloy has been specially designed to offer you increased resistance compared to the famous 8740. It can withstand pressure peaks of up to 220,000 psi. The ARP 2000 is often used for engines being in very intensive disciplines like the circuit or the dragster or the drift.
• L19 : This so-called "premium" category steel has undergone successive treatments which gives it a much higher resistance than ARP 2000 (260,000 psi). L19 steel solutions are often installed in very extreme applications on circuit and in dragster and on high very high efficiency engines. However, like ARP 2000 and 8740, L19 is particularly sensitive to corrosion and therefore requires somewhat special precautions.
• Custom Age : This new alloy designed by ARP has exceptional strength properties (up to 280,000 psi of tensile strength). The Custome Age series is Completely stainless, this alloy is exclusive and is unique to ARP . To date, it is THE best solution available and available on the market.
